Abstract

The quality of a fuel-air mixture shall be evaluated by a process and a device during a phase of combustion, especially in a spark ignition engine, in order to make possible a low-emission, fuel-saving and knock-free operation. An electrical testing pulse P is sent for this purpose to the spark plug during the phase of combustion V following the ignition pulse Z. The effect of the actual fuel-air mixture of the combustion chamber on the testing pulse is detected and evaluated as an electrical variable.
